Pretty sure it's Americauna cross, but hen or roo?

I just got 3 new birds from auction, they all look like Americauna crosses. This one I think may be a roo....not too sure so looking for any help. Tail feathers not in pic bc I had to remove (it) from coop. Other hens pulled all feathers and pecked (it) pretty bad. Medical issue is taken care of.

That's what I thought! Which concludes why my older hens are picking on him. He's now with my auction rescue with the bad foot. So hopefully once he's mature and healthy again, he can go back in with the girls.
